Fix spoiler interactions with links and long clicks (#1129)

* Prioritize clicks on hidden spoilers over links

Extend BetterLinkMovementMethod to override selection of span that will be
touched and give spoilers and links following priorities:
1. Hidden spoiler
2. Non-spoiler span (i.e. link)
3. Shown spoiler

#609

* Ignore long clicks on spoilers

Ignore long clicks if it is a SpoilerSpan. Also don't apply highlight
because it breaks spoiler effect.
